Installation Instructions Drain joint installation Drilling a hole in the wall Heat pump units require a drain joint. Before bolting the outdoor unit in place, you must install the drain joint at the bottom of the unit. Note that there are two different types of drain joints depending on the type of outdoor unit. You must drill a hole in the wall for the refrigerant piping and signal cable that will connect the indoor and outdoor units. If the drain joint comes with a rubber seal (see Figure 10, pos.
Installation Instructions Connecting Multiple Capacity Indoor Units When different capacity units need to be connected, it is recommend to connect the one has highest capacity at the bottom and the smallest unit at the top of the ODU refrigerant connection manifold. For example, if the system has one 9K, 18K, and 24K Indoor units, the 24K indoor unit should be connected via the port A. and the 9K indoor unit should be connected via the port C. (See Fig.
Installation Instructions 7 Refrigerant Piping Connection NOTICE: Be extra careful not to damage, kink, or deform the pipe while cutting. This will drastically reduce the heating efficiency of the unit. WARNING: All field piping must be completed by a licensed technician and must comply with the local and national regulations.
Installation Instructions 4. Remove tape from ends of pipe when ready to perform flaring work. Step 4: Connect pipes 5. Clamp flaring block on the end of the pipe. The end of the pipe must extend beyond the edge of the flare form in accordance with the dimensions shown in the Table 10. Connect the copper pipes to the indoor unit first, then connect it to the outdoor unit. You should first connect the low-pressure pipe, then the high-pressure pipe. Flaring tool 1.
Installation Instructions MINIMUM BEND RADIUS Carefully bend the tubing in the middle according to the diagram below. DO NOT bend the tubing more than 90° or more than 3 times. Radius 4 in (10 cm) or more Figure 18 6. After connecting the copper pipes to the indoor unit, wrap the power cable, signal cable and the piping together with binding tape. DO NOT intertwine signal cable with other wires. While bundling these items together, do not intertwine or cross the signal cable with any other wiring. 7.
